## 実装内容
### HC012: Dead Static Box
- 未参照static boxを検出
- IR boxes配列活用、calls情報から参照チェック
- テスト: HC012_dead_static_box/{ok,ng}.hako + expected.json
### HC013: Duplicate Method
- 同名・同arityメソッド重複検出
- Box内でメソッド署名の一意性チェック
- テスト: HC013_duplicate_method/{ok,ng}.hako + expected.json
### 🔥 Critical Bug Fix: parser_core.hako arity計算修正
- **問題**: arityが「カンマの数」を返していた（add(a,b) → 1）
- **修正**: `if any == 1 { arity = arity + 1 }` に変更
- **影響**: 全メソッドのarity計算が正しくなった（HC015等に波及）
### Infrastructure改善
- analysis_consumer.hako: _ensure_array()ヘルパー導入
- MapBox.get().push()問題の根本解決
- uses/methods/calls/boxes全てで安全なpush実現
- run_tests.sh: NYASH_JSON_ONLY=1で出力純度確保
- cli.hako: HC012/HC013統合、デバッグ出力追加
## テスト結果
✅ HC011_dead_methods: OK
✅ HC012_dead_static_box: OK
✅ HC013_duplicate_method: OK
✅ HC016_unused_alias: OK

# Hako Check — Diagnostics Contract (MVP)
|
|
|
|
This tool lints .hako sources and emits diagnostics.
|
|
|
|
Diagnostics schema (typed)
|
|
- Map fields:
|
|
- `rule`: string like "HC011"
|
|
- `message`: string (human-readable, one line)
|
|
- `file`: string (path)
|
|
- `line`: int (1-based)
|
|
- `severity`: string ("error"|"warning"|"info"), optional (default: warning)
|
|
- `quickFix`: string, optional
|
|
|
|
Backwards compatibility
|
|
- Rules may still `out.push("[HCxxx] ...")` with a single-line string.
|
|
- The CLI accepts both forms. String diagnostics are converted to typed internally.
|
|
|
|
Suppression policy
|
|
- HC012 (dead static box) takes precedence over HC011 (unreachable method).
|
|
- If a box is reported by HC012, HC011 diagnostics for methods in that box are suppressed at aggregation.
|
|
|
|
Quiet / JSON output
|
|
- When `--format json-lsp` is used, output is pure JSON (pretty). Combine with `NYASH_JSON_ONLY=1` in the runner to avoid extra lines.
|
|
- Non-JSON formats print human-readable lines per finding.
|
|
|
|
Planned AST metadata (parser_core.hako)
|
|
- `boxes[].span_line`: starting line of the `static box` declaration.
|
|
- `methods[].arity`: parameter count as an integer.
|
|
- `boxes[].is_static`: boolean.
|
|
|
|
Notes
|
|
- Prefer AST intake; text scans are a minimal fallback.
|
|
- For tests, use `tools/hako_check/run_tests.sh`.
